A crash fix is available in the support channel's pinned messages here: Discord.gg

please tell us; Why during play the game automatically exit and shows the error Technical Difficulties....

You have encountered a serious error. Serious errors can be caused by many things like viruses, overheated hardware, hardware not supporting the minimum system requirements...blah..blah...
This may happen after half an hour of playing or hour

This error has nothing to do with the mod. From my understanding is this an error in the core of Generals. It always have and always will be there. The contra mod however can make this error happen more frequent.

Don't forget to read the installation instructions above (click on Read more...). I made several fixes to the launcher, so hopefully you won't have issues this time. If you want to celebrate with us, join us in Tunngle (Contra 009 room). Have fun with Contra!

In my opinion the removal of the fire ports on the gun buggy is a loss. Mixing all kinds of buggies was a very efficient way of performing hit and run, which is obviously the way Prince Kassad was meant to be played. Maybe you can keep it as an upgrade in the later tech tree, if you want to balance it out in the early game?

Buggies with fireports are good only in early game. At rank 3, they are useles vs any r3 enemy unit. And in early game, they are simply op. GLA can build factory very fast, and load them with rpgs, such buggies will destroy any usa or china dozer which tries to expand early. Not only this, they can destroy china supply trucks too. They simply deal too much damage early and almost guarantee vicotry. Now you need a bit more micro, unload rpg troopers if you want to use them, but also, troopers are vulnerable when out. Even dozer can crush them. So, according to our many tests, this is the most balanced version of buggy. Same goes for Valanx, 2 of them with rpg-s can block any tunnel and rape huge number of units comming out from tunnel. Trust me, it is more balanced than before.

I highly disagree that fireports are useful only in the early game here. After Palace's upgrades to rockets and snipers they were good in mid and late game, supporting the mortar/rocker buggies' low ability to do good damage while on the move. More micro oriented plays are great, but now it makes more sense to use terrorists instead. Besides, Gun buggies are capable of killing dozers and supply trucks by their gun very efficiently without any need for infantry in them. The Valanxes were always made out of paper, and a couple of rpgs could easily snipe them. Besides, most of GLA's Scorpions have either a rocket or a powerful gun, both of which are fairly efficient vs single targets such as Valanxes.
Then again, if you see it this way, so shall it be.

Gun Buggy is good only for scout and destroying Usa Spy drones. But as you say that they are useful after rank 3, it is not true. That is weakest unit at that stage of the game. You can't even destroy toxin tractor with it, I would not mention Overlords, F35, Marauders etc...

Depends on a situation and your army mix. Mixing all sorts of buggies would give Gun Buggies a good potential to survive and deal damage and constantly kiting enemy units is quite effective versus ground. And I say ground because buggies have no anti-air potential whatsoever. When buggies are microed well, they become a force that can easily chip off enemy units with little to no backfire. Or, well, they used to anyways.

Still though, the point was to balance them in early game, and it was done, I guess. But seriously, I'm confused by this decision. Why would Battle Buses be in the game then? They too are pretty useless and not cost efficient as they are after rank 3.

Again...in later stage of game, you would simply lose too much time on micro for buggy, which can be dead from one overlord shot, or paladin, or any higher rank unit. Battle bus is kept as ambush surprise unit, cause he can store much more infantry. If you sneak one of them, you will have the chance to destroy one or two structures such as supply. But, i doubt you will sneak 5 buggies at the same time (because they cant be stealth while moving, while bus with gps can).

Sealed101, I hope you are saying all those things by your experience from mutiplayer games. If so, be free to join and play with us. We are very happy to bring more people to test this Beta 2 version and make Final better.

I was using the information I've gathered while playing numerous multiplayer games with a couple of my friends.
I will gladly join the network when I will be free and willing to. Meet you on the battlefield then! :D

Q:Removed the fire ports on the gun buggy: seriously, why?
A: Because gun buggy was OP at early game, put 2 RPGs and rape dozers.. Than you force usa to build Sec systems which cost $700 and it's big investment in that stage of game. While you can move around a map.
Q:Ratel II without jammer beam: Why?
A: Because sometimes can cause mismatch and also he does not need beam that much because he is stealth even when he shots.

This MOD is awesome and we are playing this mod for several months now with my co-workers, we play this thru LAN. Sometimes versus AI or most of the time 2B2, so we encounter serious error during start of the battle or in the middle of the game it says "Mismatch due to blah blah blah! etc.."..

What is the main reason for such error? Our conclusion maybe in one laptop that we are using is delayed sending communication, like if there are more armies, tanks, helicopters, etc... So the tendency most of the time are lag..

Certain parts of the mod's code could cause mismatch. This can be confirmed by online players when a specific action (such as using a general's power) triggers a mismatch instantly or after very few seconds. What we can do about it is revise parts of the code so that it doesn't trigger the mismatch error.

Other times mismatch can occur randomly by itself. Exact reasons are unknown and nobody has found a way to avoid it yet. We have to deal with it.

Last error:
Exception is access violation
WinMain at 401720
Error code: EXCEPTION_ACCESS_VIOLATION
Description: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.
Access address:00000064 was read from.

To begin ... Happy Holidays.
Installed the game, normal voice or the other , i get the same problem..
Game ends abrupt with 'Technical error' after aprox 10 min. playing against just 2 AI on hard. Myself as GLA assult, the 2 AI as Laser and Tank.
I didn't have that with the previous version, so the best would be to take that one again.
